Transfer your contacts from your compatible Nokia device to your Nokia N900 by following these easy steps. First tap
and select Contacts. Then open the menu and select Import > Synchronise from other device > Next.

Now choose whether you want to transfer your contacts from another Bluetooth device, or you can enable synchronisation to keep your contacts up to date on both devices. Make your selection and tap Next.
The next step is to select Choose device and then the desired device from the list. Enter the identification number of the device you want to transfer data with, and select Pair.
To synchronise your Nokia N900 with a non-Nokia device, either copy your contacts from the SIM card or simply import the contact file.
